Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0021] Reference Figure 1 - Figure 4 As shown, this utility model provides a technical solution: a sensor probe with a protective structure, including a device body 1; a sensor probe body 2 is provided at the bottom of the device body 1, and a protective shell 3 is provided on the outside of the sensor probe body 2; an installation groove 4 is provided at the bottom of the device body 1, and the protective shell 3 is installed inside the installation groove 4. The protective shell 3 is made of high-strength plastic. L-shaped plates 5 are fixed on both sides of the device body 1, and a fixing mechanism is provided inside the L-shaped plates 5 for fixing the protective shell 3 inside the installation groove 4. By setting the protective shell 3, the sensor probe body 2 is protected by the robust outer shell of the protective shell 3, avoiding damage to the sensor probe body 2 due to accidental collision or impact, thereby ensuring its long-term stable and reliable operation, improving the service life of the sensor probe body 2, and by setting the installation groove 4 and the fixing mechanism, it is convenient to install and disassemble the protective shell 3, thereby facilitating the inspection or replacement of the sensor probe body 2.

[0022] Reference Figure 2 and Figure 4 As shown in this embodiment, the fixing mechanism includes a fixing tube 6 fixed inside the L-shaped plate 5. A movable rod 7 is slidably installed inside the fixing tube 6. A pull rod 8 is fixed to the top of the movable rod 7 and extends to the outside of the fixing tube 6. Fixing grooves 9 matching the movable rod 7 are provided on both sides of the protective shell 3. By pulling the pull rod 8, the movable rod 7 is driven to slide inside the fixing tube 6. When the movable rod 7 disengages from the fixing groove 9, the protective shell 3 can be removed from the mounting groove 4, realizing the quick disassembly of the protective shell 3. This facilitates the subsequent maintenance or replacement of the sensor probe body 2, saving time and effort and bringing great convenience to the user.

[0023] Reference Figure 4 As shown in this embodiment: a spring 10 is sleeved on the surface of the fixed tube 6. One end of the spring 10 is fixed to the inner side of the L-shaped plate 5. The end of the pull rod 8 extending to the outside of the fixed tube 6 is located at the pitch of the spring 10. By setting the spring 10, the elastic force of the spring 10 pushes the movable rod 7 into the fixed groove 9, thereby fixing the protective shell 3 and preventing the protective shell 3 from loosening or falling off during use, thus improving the stability of the device. At the same time, the design of the spring 10 also enables the movable rod 7 to automatically reset, further simplifying the disassembly and installation process.

[0024] Reference Figure 4As shown in this embodiment: a guide groove 11 is provided at the top of the fixing tube 6, and the pull rod 8 is slidably installed inside the guide groove 11. By setting the guide groove 11 to guide the pull rod 8, the pull rod 8 is more stable during movement, avoiding the phenomenon of the pull rod 8 deviating or getting stuck, ensuring that the fixing mechanism can work normally. At the same time, the design of the guide groove 11 also makes the movement path of the pull rod 8 clearer, further improving the convenience of disassembly and installation.

[0025] Reference Figure 3 As shown in this embodiment: a foam plastic ring 12 is provided inside the mounting groove 4. The foam plastic ring 12 is located between the protective shell 3 and the sensor probe body 2. By setting the foam plastic ring 12, the elasticity and buffering performance of the foam plastic ring 12 are used to further protect the sensor probe body 2. At the same time, the foam plastic ring 12 can also play a role in sound insulation and noise reduction, reducing the noise generated by the sensor probe body 2 during operation and improving the quiet performance of the device.

[0026] Reference Figure 2 As shown in this embodiment, the protective shell 3 has multiple heat dissipation holes 13 on its surface. By setting the heat dissipation holes 13, the air circulation inside the protective shell 3 is increased, so that the heat generated by the sensor probe body 2 during operation can be dissipated in time, avoiding performance degradation or damage caused by excessive temperature, and ensuring the stability and reliability of the sensor probe body 2. At the same time, the design of the heat dissipation holes 13 also makes the protective shell 3 more breathable, reduces the accumulation of internal moisture, and further extends the service life of the sensor probe body 2.

[0027] Reference Figure 2 As shown in this embodiment, the surface of the sensor probe body 2 is coated with a protective coating. By coating the surface of the sensor probe body 2 with a protective coating, the protective coating has excellent corrosion resistance, wear resistance and high temperature resistance. It can effectively resist the erosion and damage of various corrosive substances, particles and high temperature conditions in the external environment to the sensor probe body 2, thereby further improving the durability and service life of the sensor probe body 2. At the same time, the protective coating can also enhance the smoothness and cleanliness of the surface of the sensor probe body 2, reduce the adhesion of dirt and impurities, and help maintain the sensitivity and measurement accuracy of the sensor probe body 2.

[0028] Working Principle: By installing the protective shell 3, the user protects the sensor probe body 2 from damage caused by accidental collisions or impacts, ensuring its long-term stable and reliable operation and extending its service life. The installation slot 4 and fixing mechanism facilitate the installation and removal of the protective shell 3, enabling easy maintenance or replacement of the sensor probe body 2. Pulling the lever 8 causes the movable rod 7 to slide within the fixing tube 6. When the movable rod 7 disengages from the fixing slot 9, the protective shell 3 can be quickly removed from the installation slot 4, facilitating subsequent maintenance of the sensor probe body. The maintenance or replacement of the protective shell 3 is time-saving and labor-saving, bringing great convenience to the user. By using spring 10, the elastic force of spring 10 pushes the movable rod 7 into the fixing groove 9, thereby fixing the protective shell 3 and preventing it from loosening or falling off during use, thus improving the stability of the device. At the same time, the design of spring 10 also allows the movable rod 7 to automatically reset, further simplifying the disassembly and installation process. The guide groove 11 guides the pull rod 8, making it more stable during movement and preventing it from shifting or jamming, ensuring the normal operation of the fixing mechanism. Furthermore, the design of the guide groove 11 also facilitates the movement of the pull rod 8. The movement path is more clearly defined, further improving the convenience of disassembly and installation. By incorporating a foam ring 12, the elasticity and cushioning properties of the foam ring 12 further protect the sensor probe body 2. Simultaneously, the foam ring 12 also serves to insulate and reduce noise, decreasing the noise generated by the sensor probe body 2 during operation and improving the device's quietness. The heat dissipation holes 13 increase airflow within the protective shell 3, allowing the heat generated by the sensor probe body 2 during operation to dissipate promptly, preventing performance degradation or damage due to overheating and ensuring the stability and reliability of the sensor probe body 2. Furthermore, heat dissipation... The design of hole 13 also makes the protective shell 3 more breathable, reducing the accumulation of internal moisture and further extending the service life of the sensor probe body 2. By coating the surface of the sensor probe body 2 with a protective coating, which has excellent corrosion resistance, wear resistance and high temperature resistance, it can effectively resist the erosion and damage of various corrosive substances, particles and high temperature conditions in the external environment to the sensor probe body 2, thereby further improving the durability and service life of the sensor probe body 2. At the same time, the protective coating can also enhance the smoothness and cleanliness of the surface of the sensor probe body 2, reduce the adhesion of dirt and impurities, and help maintain the sensitivity and measurement accuracy of the sensor probe body 2.

[0029] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
